Abstract
Biofilters are best operated at steady loads of contaminants. Research has indicated the possibility of using a carbon filter for buffering the biofilter. To provide long-term stable operation of a biofilter, a two-bed adsorption system involving adsorption/desorption cycles was applied. The two-bed adsorption unit was designed for operating in a two-step cycle in a fixed bed of adsorbent using gas pressure variation as the principal operating parameter. The two-step cycle was employed successfully as a polishing unit to abate the initial acclimation for the biofilter and as a buffering unit to dampen the biofilter performance during a square wave change of toluene concentration. This is an abstract of a paper presented at the A&WMA's 98th Annual Conference & Exhibition (Minneapolis, MN 6/21-24/2005).
